. .IMPROVEMENT 1N LOOM ron eIBeULAR WEAVING.

TO ALL WHOM IT MAY GONCERN:

Be it known that I, ADOLPH WAGNER, of the city, county, and State of NewYork, have invented anewand improvedWeaving-Machine; and I do herebydeclare that the following is a l'u-ll, clear, andexaet deseripl tionthereof, which 'will enable others skilled-in the art to make and usethe same, reference being had to the accompanying drawings, forming partof lthis speeication, in whiehi Figure 1, sheet 1, represents ahorizontal sectional view of ny improved weaving-machine, the plane ofsection being indicated by the line x 2:, iig. 2.

Figure 2, sheet 2,`is a vertical central section of the same.

Figure 3, sheet 2,.is a detail side elevation of the warp-carrier.

i Figure-1, sheet I2,"`is a detail side' elevation of the gears forraising and lowering the warp-carriers. Similar letters of referenceindicate corresponding parts.

This invention relates *to anmproved machine for weaving hoop-skirts andother fabric of tubular ory Irregular shape, but is more particularlyintended for the manufacture of petticoats and hoop-skirts.

Theinvention consists principally in the use of a circular machine, inwhich the fabric is woven around a block, suspended between thewarp-carriers and the track of the shuttles, said block beingup-and-down as well as laterally adjustable, so that it may always beadjusted centrally between the shuttles, howsoever irregulor its shapemay be.

The shuttles move on a circular, oval, or irregular endless truck, anddeposit their woef-threads alternately aboveand below awarp-threedaround the aforesaid block.

` The warp-carriers receive :in alternato up-and-down motion by means ofa cam; which is arranged on the outside of a revolving drum, by whichdrum also the' shuttles receive their motion.

The warp-threads-have to be spread, so as to have them equidistant fromeach other around the block.

For that purpose the carriers have horizontal extensions, which arediverging, like spread fingers, so that the desired effect is produced,and the desired distance between the warp-threads obtained, withoutrequiring the spreading of thel carriers, which are arranged in groupsof six, or more or less. To diminish friction 1n the operation ofthe1carriers, such grouping' is necessary, as otherwise each carrierwould require its own connection with the earn on the drum.

, The earn only operates one set of cach group of earriers,endthecarriers, which are thus alternately raised Aand lowered, impart,byfmeans of gearing or otherwise, motion to the other set of carriers,so that the same always moves in the opposite direction with thelirst-named set.

The operation ofthe machine, and the details of' its construction, willmore fully appear from the following description, in which reference ishad to the drawings.

v A, in the drawing, represents thel frame of my improvedweaving-machine.

The frame is of suitable size and material, and carries a verticaldrrrm, B, to which rotary motion can be imparted hy means ol gear-wheelsa a, from a driving-shaft, C, or by any other suitable mechanism.

On the drum B is rnounted a toothed ring, b, which imparts motionto a.serios lof pinions, c c, that is mounted on vertical arbol-s d d, whichhave their bearings in the frame A, and which carry pinions e e on theiruppers ends, as is clearly shown in figs. 1 and 2..

'lhe upper ends of the arbors cl d and the pinions e e are protected bycovering-plates ff, which are attached to theframe A, as is clearlyshown in lig. 2.

'lo the lower part of the frame A are secured horizontal bars gg, whichform shafts for bobbins D D, upon which the warp-threads are wound..These threads are placed over railsh h, und through loops in carriersEE, by which they are held the required distance apart.

From tho frame A project two uprights F F, between which a cross-bar, G,is held. In this cross-bar is arranged a mit, 1', which islongitudinally adjustable in the bar G, either by means of a scrcw,j, orotherwise.

arias 2 This block forms the core of the fabric to bo woven, andis ofthe required shape.

The ends oi the warp-threads` are fastened to the upper or lower end ofthe block H, and it is necessary that thewarp-thrends should all-bcequally far apart from each other. 5 For that purpose the carriers Eshould be also equally far apart.

As the woef-threads have to pass between the warp-threads, as thelattcrhavo to be alternately raised and Through the nut z' is fitted a.vertical screw, Ic, from the lower end of which a. block, H, issuspendedA lowered to form the required nettingin the fabric, and as,therefore, thewarpthreads must heiabletoplay below as well as abovethcshuttles of the woothreads, and as, iinally,..the said wooithreadsare about on a. plane with the pinions c, it is necessary that thewarp-threads should be able to play higher and lower than the pinions e,As the latter are covered by .platesji the warp-thre`adscould vnot bemoved down, it they were distributed equally fax: apart over, the wholeframe A. Therefore the warp-threads have to be collected 'in the spaceswhich are between the several platesf, and -nuust then be distributed:is desired.

The warp-thread carriers E are L-shapcd bars, theirvverti'cal armsbeing' toothed, as shown, while their horizontal arms have loops Z l,for the warp-threads to pass, through. All .the horizontal arms of thecarriers which are groupedtogether between every two plates, ff, aresecured to two upright arms, so that, if there are six carriers betweentwo plates,f, three project from'oncLand the others from theotliciy'upriglit nrm, as is' clearly shown in the drawing; or eachhorizontal arm projects from its'own upright arm, butthrce of the latterare.

connected at their lower ends, as indica-ted inigrfl.

The lower parts of thc upright arms of the carriers are toothed, asshown; and of the two uprights which. support a group of carriers, oneis toothed -onrtli'e right, and the other 'on the left-hand edge, as isclearly shown` in Eg.4. l l i 4' The two uprights of ono group' meshwith theirteeth intoa pinion, m, as shown, and one of the uprights has apimp, which fits into acum-groots!- th'a; is arranged aroundfthelrotarydruinB, as in iig. 2, or is otherwise connected with a cam-rail orgroove on the drum, sothat it is alternately raised and lowered duringthe' revolutions of the drum.

By being connected, by means of the pinion n.1, with the otheriupright,the moved carrier imprts motion to the other carrier, but in oppositedirection, so that one moves up when the other moves down, and viceversa, and thus each `halt' of the carriers between every two plates, f,moves simultaneously with `the other half, but in the oppositedirection. v

The horizontal arms of the carriers E of cach group are interposedbetween each other in such a manner that always one of one stem is nextto oneofthe other stem, and thus, throughout the whole machine, eachWarp-thread is moved up while the warp-threads adjoining it move down,and down when they are moved up.

' The threads are distributed equally far apart, by bending thehorizontal arms of the carriers, so thatthe desired effect ispreduccdbetween the pinions c and the block II, as is clearly shown in fig. 1.

In place of the carriers E, when they are arranged as described, anotherdevice may be employed. In this the carriers would only consist ofupright arms E E', iig. 2, arranged in groups, like the others, and halfof each group connected at the lower end, and by means of anpinion, m,with the other half, and by the pinp with the drum, as shown. f v Y Theworp-threads are drawn through loops in the upper ends of thereciprocating stems E', as shown, and are then separated and distributedor spaced, as required, by being-drawn through sliding blocks o o, which't between upright bnrs I I, so that they can easily move up and downbetween the same. As these bars are 1in the way ofthewof-threacls,-thcre has to be a space provided for the woof to passthrough, and for that purpose the bars are separated in about themiddle, as in tig. 3, their respective parte projecting upward from aplate,

Vn, and downward from an upper plate, q, as shown.-

'Ihe spaces between the two parts ot` each har, I, are not too long, sothat the blocks may not slip out of their places while they move up anddown with the carriers Eywith which they are connected by means of, thethread.y l I The woef-threads, which maybe wire or steel springs,similar to those used in hoop-skirts, or silk or other threads, arewound around bobbins J J, which turn on pins 1' r, that project fromshuttles L.

'.lhe shuttles are metal plates, with toothed downward projections s s,of such length that each shuttle always meshes into at least one of thepiirions e, as shown in fig. 1. l

Thus, ns the drum B rotates, the vpinions e will also revolve, andthereby the shuttles L will be moved upon the platesf, around the blockH, and lwill deposit their threads around the block H., as shown. Thewooithrearls receive ythe proper tension b v means of springs t t, whichpress against the hobbins J, as shown.

'lhc operation will be easily understood. 'lhe block II remainsstationary during the revolutions of the drum B, except that itA isadjusted up or down to the required height, which may bc doneautomatically, by connecting the screw with suitable mechanism for thatpurpose. 'lhe block His also adjusted horizontally, by moving'the nut z'on Athe bar G, so that that portion of the said block which is receivingthe threads may always be kept equidistant from the shuttles` l and asnear as possible concentric with the drum B.

Each woef-thread is,` as it passes through the warp-threads, laidalternately over and under a warp-thread, as is indicated in fig. L Y -1v This machine may also b'e vemployed for weaving other than endlessfabric, by imparting to tho shuttles a reciprocating instead of anendless motion.

'.lhe pinp may be mudo sliding on the carrier-stem, as shown, so thatany one group oficarriors may at once be thrown out of gear, Wheneverdesired. i

Having described my invention, l claim :ts new, :md desire to securebyLetters Patent- 1.
